The 18-game streak ties the seventh longest in NBA history, and is the league's best since the Boston Celtics won 19 straight during the 2008-09 season. Miami will try for No. 19 when it hosts Atlanta on Tuesday night.

The win also gave Miami (47-14) a victory over every NBA team this season. The Heat lost both previous meetings with Indiana.

Dwyane Wade scored 23 points for the Heat, who controlled the game despite a season-low 13 points from LeBron James. Ray Allen added 11 for Miami.

David West scored 17 of his 24 points in the first half for the Pacers, who fell nine games behind Miami in the Eastern Conference standings. Roy Hibbert scored 15, D.J. Augustin had 14 and Paul George scored 10 for Indiana.

RAPTORS 100, CAVALIERS 96: At Toronto, Amir Johnson scored 17 points and matched his career high with 16 rebounds, and Alan Anderson scored 10 of his 18 points in the fourth quarter.

Cavaliers star guard Kyrie Irving was knocked out by an apparent shoulder injury late in the third quarter as Cleveland lost for the fourth time in five games.

Irving was hurt when he collided with Toronto rookie Jonas Valanciunas on a baseline drive with 2:04 left in the third. He shot the resulting free throws one-handed. Irving made the first but missed the second before walking off and heading to the locker room. He finished with 12 points.

Irving missed 11 games between Nov. 21 and Dec. 8 with a broken finger. He also sat out three games between Feb. 26 and March 1 with a sore right knee.

The Lakers improved to 33-31, the first time this season they have been two games over .500. They also moved one-half game ahead of the Utah Jazz and into sole possession of the No. 8 and final playoff spot in the Western Conference.

Nate Robinson led the Bulls with 19 points, and Joakim Noah had 18 points and 17 rebounds.

Arron Afflalo and Tobias Harris added 17 and 15 points, respectively. The double-double was the 35th of the season for Vucevic.

Thaddeus Young had 26 points and 12 rebounds for the Sixers, followed by Damien Wilkins with 16 points in his first start of the season.

HORNETS 98, TRAIL BLAZERS 96: At New Orleans, Ryan Anderson capped a 20-point performance with a layup as he was fouled with 1.8 seconds left, and the Hornets snapped a three-game skid.

Anderson also hit a 3 with 15.6 seconds left that gave the Hornets a 95-93 lead, but Portland rookie Damian Lillard reached the 20-point mark for a sixth straight game by draining a 3 with 11.2 seconds left.

Greivis Vasquez, who also had 20 points, then dribbled out of traffic along the perimeter and found Anderson inside for the winning bucket.

Brandan Wright added 13 points and seven rebounds for the Mavericks, who have won three straight and four of their last five in a last-ditch push for the playoffs. They entered the day in 11th place in the West, three games out of the eighth spot.

Derrick Williams had 18 points and nine rebounds for the lethargic Timberwolves, who had no energy on the second night of a tough back-to-back that started in Denver. J.J. Barea scored 16 points, but Minnesota's bench managed just six other points. The Wolves are 6-25 since Kevin Love broke his hand for the second time on Jan. 8.
